Struct sp_io::UseDalekExt
source · pub struct UseDalekExt;Expand description
Extension to signal to [crypt::ed25519_verify] to use the dalek crate.
The switch from ed25519-dalek to ed25519-zebra was a breaking change.
ed25519-zebra is more permissive when it comes to the verification of signatures.
This means that some chains may fail to sync from genesis when using ed25519-zebra.
So, this extension can be registered to the runtime execution environment to signal
that ed25519-dalek should be used for verification. The extension can be registered
in the following way:
client.execution_extensions().set_extensions_factory(
// Let the `UseDalekExt` extension being registered for each runtime invocation
// until the execution happens in the context of block `1000`.
sc_client_api::execution_extensions::ExtensionBeforeBlock::<Block, UseDalekExt>::new(1000)
);

Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>

fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.source§impl<T> Instrument for T
